Abstract
An apparatus and method for determining an uplink channel used for a random access procedure are provided. An exemplary method by a User Equipment (UE) includes transmitting a preamble to a Base Station (BS) on at least one channel of a plurality of channels, receiving a response from the BS, and distinguishing the response based on an identifier unique to a channel resource to identify the channel in which the preamble is transmitted.
